PhiEthHooks

BaseRegistered

A Uniswap v4 hook that implements a custom 1:1 ETH/phiEth swap curve using beforeSwapReturnsDelta, bypassing AMM price math entirely. It takes the input from the PoolManager, converts via the phiEth contract (deposit or withdraw), and settles the output — all within beforeSwap. Direct liquidity additions are permanently blocked.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
